Provided is a refresh method of a volatile memory device. The method includes: detecting a number of disturbances that affect a second memory area as the number of accesses to a first memory area is increased; outputting an alert signal from the volatile memory device to an outside of the volatile memory device when the detected number of disturbances reach a reference value; and performing a refresh operation on the second memory area in response to the alert signal.
